| AR Classic 60 Bias Confusion Adjust the "bias" for an average reading of 65 mVDC (0.0650 volt DC) between TP1 - TP2 and between TP3 - TP4. Do not make any other adjustments of pots in the amp. For power tube bias adjustments go to pages 7 and 8. https://www.arcdb.ws/D... | |
| Dedicated power circuits I don’t like MC cable or wire in a steel pipe. I agree with your statement for use of steel armored MC cable or loosely pulled conductors in a steel conduit for the reasons you stated in your post dated 02-24-2023. I do like and recommend 2 wi... | |
| Dedicated power circuits I had to have the second phase run at Fremers because I could not get a letter from SqD saying a Square D subpanrl rated 120/240 was suitable for 120 only. That jogged my memory. Sounds like the Electrical Inspector was using NEC 110.3 (B). Squ... | |
| Dedicated power circuits @8th-note, . ~ ~ Is this what you are looking to buy? You do know it is 120/240V? Best practices is to feed audio equipment, (that is connected together by wire ICs), is to feed the 120V equipment from branch circuit breakers fed from... | |
| Left RCA out on DAC not working @painter24 said: I feel it maybe as you say; the AECO’s longer center pin may have damaged the jack. . I’m kind of resigned myself with it as I am getting a replacement, but it’s just the wait. Just a suggestion. You might as well conti... | |

| Left RCA out on DAC not working @painter24, Just to narrow the problem down to the DAC left channel RCA analog out jack did you try another set of Line inputs on the preamp to make sure it's not that left channel input that causing the problem. Or even try swapping the right ... | |

| Left RCA out on DAC not working The AECO plugs have no metal on the plug shrouds inside, apart from the pin, whatsoever. @painter24,, Is this what the plug looks like? I can see the signal ground contact on the bottom of the inside of the plug "shroud". Look at the bottom of... | |
| Left RCA out on DAC not working The DAC is relatively new; I contacted the distributor, and he thinks it’s a badly soldered ground on the inside of the chassis. If that is the case then why would the Lavri Grand ICs that have AECO plugs work? The AECO plugs have a metal strip... | |

PX-2 Power Supply Input Only use a Line 6 PX-2 power supply when powering your Micro Spider using the AC IN connection. "AC in connection." I have no idea if the circuitry inside the amp c... | |

| Amp biasing question @immatthewj Depends on what your intentions are. Are you planing on only checking the tube bias and then shutting the amp off and not listening to music, Then there is not any need to turn on the preamp. If you want to check the bias and then ... | |
| Wiring 2 outlets to 2 dedicated 20 amp circuits with a single 10/3 electrical wire. @rbertalotto said: So, are you saying both circuits should be run from the same leg on the panel rather than one circuit on each leg? I plan on running two 12/2 - 20amp circuits, 24’ and terminate in two quad outlet boxes......Yes/OK? And, if ... |
